Hello list, Today I started Pig on my personal machine after a few weeks to give 0.11.1 a try. As soon as I issued bin/pig it threw this message on my terminal :
apache@hadoop:/hadoop/projects/pig-0.11.1$ bin/pig 2013-06-26 06:05:45,121 [main] INFO org.apache.pig.Main - Apache Pig version 0.11.1 (r1459641) compiled Mar 22 2013, 02:13:53 2013-06-26 06:05:45,122 [main] INFO org.apache.pig.Main - Logging error messages to: /hadoop/pig/logs/pig_1372206945120.log 2013-06-26 06:05:45,143 [main] INFO org.apache.pig.impl.util.Utils - Default bootup file /home/apache/.pigbootup not found 2013-06-26 06:05:45,256 [main] INFO org.apache.pig.backend.hadoop.executionengine.HExecutionEngine - Connecting to hadoop file system at: maprfs:/// 2013-06-26 06:05:45,326 [main] INFO org.apache.hadoop.util.NativeCodeLoader - Loaded the native-hadoop library 2013-06-26 06:05:45,327 [main] INFO org.apache.hadoop.security.JniBasedUnixGroupsMapping - Using JniBasedUnixGroupsMapping for Group resolution 2013-06-26 06:05:45,385 [main] INFO org.apache.pig.backend.hadoop.executionengine.HExecutionEngine - Connecting to map-reduce job tracker at: maprfs:/// I was quite surprised at the first look, but then realized that I was checking out MapR's M3 on my machine a few days ago. Is is normal?I mean Apache Pig is going to "maprfs" instead of "hdfs" despite the fact that all my Apache Hadoop daemons were running. Although I removed M3 immediately, i'm still curious. I would really appreciate if somebody could shed some light. Thank you so much for your time. Warm Regards, Tariq cloudfront.blogspot.com
